public string getPageCode(string url, Encoding Encode)
 {
       string strHtml = string.Empty;
        HttpWebResponse wresp;
        try
         {
                //连接到目标网页  
                WebRequest wreq = WebRequest.Create(url);
                wresp = (HttpWebResponse)wreq.GetResponse();
            }
            catch (WebException ex)
            {
                wresp = (HttpWebResponse)ex.Response;
            }
            //采用流读取，并确定编码方式  
            StreamReader objReader = new StreamReader(wresp.GetResponseStream(), Encode);

            return strHtml = objReader.ReadToEnd(); 

  }

方法调用

getPageCode(url, Encoding.GetEncoding("gb2312"));

发这些东西就是为了以后用的时候方便，如果有不对欢迎指出。
